A millennium. Sanaa has been separated from her family for a millennium. Sadly, the reunion doesn't last ling and she is thrown into the Fae Courts to open her eyes and finally see that things have changed in ways that she could have never imagined. A job. August has been working alongside Helia for years now. By her side, August has fully embraced what it means to be a demon. So when he is assigned a job to assimilate a faction that lays in the Fae Courts. He does it without thought. A duty. Taira has looked over the town of Asren for decades, nothing escapes her watchful eye. But when a new threat rises Taira finds herself in need of new allies to help her face down this new foe. All three gather in the town of Asren to face a threat that gathers in the darkness and puts at jeopardy not only the town but the whole world of Ettrea.

A dark power. Sanaa is bound, force to serve to the Fae Empress, Sorcha's, will. Her dark power lingers inside of Sanaa forcing her to follow the empress to the capital of the Fae the Citadel. A challenge. August and the others are not in the Citadel for long before Nova makes her next move. They are sent out to find Argentau, the mythical waters that claim to allow anyone to look into the future—or the past. A promise. Aregntau promises insight into the threat that is Nova. But it also promises insight into new threats and dangers Taira and the others will face. The clock ticks on as they must reach Argentau and hope to discover what Nova is planning before it is too late.

A death. Sanaa is dead and August and Taira have to pick up the pieces. August leads the vanguard to the Winter Court where the Winter Queen waits for them to fight off Nova and their army. A life. Taira is still reeling from the death of Cinder's grandfather and the rejection that she received from Cinder. Left to raise Cinder's younger cousin, she focuses on honing him into a knight and finding her own way in the world. A choice. Cinder is happy. She is in the place of power and Sorcha values her as the only lady in waiting that the empress has. And now the Crown Prince Paul is here and Cinder is gunning for the seat of Crown Princess. But her dreams are haunting her and she has the itching feeling that something is not right. Something is wrong, but power is all she ever wanted, right? With their lives irrevocably changed, Cinder, August, and Taira trudge on, hoping that the reaper doesn't come for them next.
